Abstract
A non-slip shoe wear has a non-slip part on each of an inner surface and an outer surface. The non-slip shoe wear can prevent an injury to the skin while maintaining a non-slip function by alternately arranging a non-slip part of an inner surface and a non-slip part of an outer surface.
Claims3
A non-slip shoe wear having an inner surface part (1a), which is configured to, when in use, come in contact with a foot of a wearer, on a sole of a shoe wear body (1) in which the wearer's foot is accommodated, and an outer surface part (1b) beneath the sole, wherein the inner surface part (1a) is composed of inner non-slip sections (10) made of a material for preventing a slip, and inner slip sections (20) that are sections where the inner non-slip sections (10) are not formed;
- the outer surface part (1b) is composed of outer non-slip sections (30) made of a material preventing a slip, and outer slip sections (40) that are sections where the outer non-slip sections (30) are not formed;
- and the inner non-slip sections (10) and the outer non-slip sections (30) are alternately arranged not to vertically overlap in a side cross-section;
- wherein a plurality of column cells (71) having a tumbler shape having an inner diameter of a distal end larger than an inner diameter of a close end portion from a portion fixed to the shoe wear body (1) are formed on each of the outer non-slip sections (30) and the inner non-slip sections (10), and the outer non-slip sections (30) and the inner non-slip sections (10) are each made of a wet-type polyurethane sheet (70) having non-slip grooves (72) that entirely or partially communicate with column cells (71) are formed on a surface of a distal end side from the portion fixed to the shoe wear body (1);
- and
- wherein the wet-type polyurethane sheet (70) is bonded to the shoe wear body (1) through a hot-melt bonded layer (73);
- an end of the hot-melt bonded layer (73) is positioned inward further than an end of a wet type polyurethane sheet (70) constitution the inner non-slip sections (10);
- and the wet-type polyurethane sheet (70) is composed of a center bonded layer (11) bonded to the hot-melt bonded layer (73) and an outer non-bonded layer (12) of which an edge is not bonded to the hot-melt bonded layer (73), thereby forming an upper drain space (90) spaced apart from the shoe wear body (1).
A non-slip shoe wear having an inner surface part (1a), which is configured to, when in use, come in contact with a foot of a wearer, on a sole of a shoe wear body (1) in which the wearer's foot is accommodated, and an outer surface part (1b) beneath the sole, wherein the inner surface part (1a) is composed of inner non-slip sections (10) made of a material for preventing a slip, and inner slip sections (20) that are sections where the inner non-slip sections (10) are not formed;
- the outer surface part (1b) is composed of outer non-slip sections (30) made of a material preventing a slip, and outer slip sections (40) that are sections where the outer non-slip sections (30) are not formed;
- and the inner non-slip sections (10) and the outer non-slip sections (30) are alternately arranged not to vertically overlap in a side cross-section;
- wherein a plurality of column cells (71) having a tumbler shape having an inner diameter of a distal end larger than an inner diameter of a close end portion from a portion fixed to the shoe wear body (1) are formed on each of the outer non-slip sections (30) and the inner non-slip sections (10), and the outer non-slip sections (30) and the inner non-slip sections (10) are each made of a wet-type polyurethane sheet (70) having non-slip grooves (72) that entirely or partially communicate with column cells (71) are formed on a surface of a distal end side from the portion fixed to the shoe wear body (1);
- and
- wherein the wet-type polyurethane sheet (70) is bonded to the shoe wear body (1) through the hot-melt bonded layer (73);
- the wet-type polyurethane sheets (70) constituting the inner non-slip sections (10) have a square shape and are spaced apart from each other transversely and longitudinally in the shoe wear body (1);
- the hot-melt bonded layer (73) bonding the wet-type polyurethane sheets (70) constituting the inner non-slip sections (10) and the shoe wear body (1) has a circular shape is inscribed to the square polyurethane sheets (70);
- the wet-type polyurethane sheets (70) constituting the inner non-slip sections (10) are composed of the center bonded layer (11) bonded to the hot-melt bonded layer (73) and the outer non-bonded layer (12) forming the upper drain space (90) spaced apart from the shoe wear body (1) without a bottom bonded to the hot-melt bonded layer (73);
- and the outer non-slip sections (30) are disposed between adjacent inner non-slip sections (10) in a plane.
